APPLICATIONS IN ACTION
One antenna class. Multiple real-world wins.
Constellation TT&C:
High isolation and stable gain support predictable, repeatable links across frequent LEO passes, enabling scalable operations with reduced RF and integration complexity.
Multi-RF SmallSats
>30 dB port-to-port isolation helps shield sensitive receivers from high-power Tx interference, making it ideal for platforms carrying multiple radios or RF payloads in tight volumes.
Earth Observation & High-Value Payload Missions
Provides a clean, resilient S-band command-and-health lifeline for safe mode and routine control, where mission assurance depends on rock-solid TT&C.
Full-Duplex Operations
Purpose-built Rx/Tx separation and geometry minimize desensitization risks, supporting efficient commanding and telemetry flow when short contact windows demand simultaneous links.
